WALL CONSTRUCTION.

Speccation of Letters Il-"ai'iei'it Patented June 23, 1908.

Application led July 31, 1906. Serial No. 328,504.

To all whom 'it may-'concern' Be it known that 1, SILAs CRAWFORD CoY- NER, a citizen of the United States, residin r at Overton, in the county of' Dawson and State of Nebraska, have invented new and useful 'liiiproveinents in Wall Construction, of which theI following is a specilication.

This invention relates to a wall construction, and has for its object to produce a wall having a dead-air space from top to bottom,

` andit consists in forming the wall ol' blocks which are spaced from eachother and connected by a tie block.

- In the accompanying drawing, Figure 1 is a perspective view of the/wall constructed in accordance'with the invention. Fig. 2 isa plan View thereof. Fig. 3 is a vertical section on the line 3-3 of Fig. 2. Figs. 4, 5 and 6 are perspective views of the blocks cinployed.

Referring specifically tothe drawing, the

wallis formed by outer blocks 10 and inner blocks 11 which are laid a suilicient distance a art to leave an air space in the wall.- The blbcks are connected by tie blocks 12. The blocks 10 and 11 are rectangular in shape,

and in the inner face of each of the blocks- 10 is a recess or seat 13, the side-walls 14 of which are inclined. By having the sides inclined the tie blocks will fit therein notwitlistanding any possible slight variation in the spacing of the joints or laying of the blocks. The recesses extend downwardly from thc I i top of the block to about the middle thereof,

and its sidewalls 14 as well as its bottom 15 are undercut.

The blocks 11 are out away at each end as at 16 to forni seats 17 for the tie blocks. The walls of the seats thus formed are also inclined and undercut similar to the walls of the recesses 13. The wall sections will be laid to break joints so that the joint between the blocks 11 is at the middle of the blocks 10 which brings the seats 17 opposite the recesses 13.

The tie block` 12 is'T-shaped and when in position its stem 18 extends between the blocks 10 and 11 and spaces the sameapart, as well as acting as a binder, and its branches 19 extend into the seats 13 and 17 respectivel The under sidesof the branches are beve ed to correspond to the undercut portion of the walls of the seats. This produces dovetail joints between .the blocks whereby the wall sections are securely bound together and etfectually prevented from spreading. At vthe corner ,of the wall an outer block of lialf-length is used on one side which is connected to t e inner wall section in the same manner as t e other blocks. The tie-blocks however is only one-half the width of the others.

With the blocks hereindescribed a strong and rigid wall is formed with a continuous air space from top to bottom. All joints will be set in mortar.

I claim section composed of blocksr having recesses in their rear faces, the side walls of the recesses being inclined, and an inner section composed of blocks which are cutaway at their ends to forni seats which are opposite the aforesaid recesses, and tie blocks between tlie wall sections and extending into the aforesaid recesses and seats.

2. Awall construction com rising an outer section composed of blocks iaving recesses in their rear laces extending partly down the block, and an inner section composed of blocks which are cut away at their ends to forni seats which are opposite the aforesaid recesses, and tie blocks between the walls extending into the recesses and seats, and having depending stems fitting between the blocks below the recesses and seats.

In testimony whereof I have signed my siLAs CRAWFORD eoYNER.
